Heuristics and Biases: Cognitive Shortcuts in Human Judgment
Heuristics and biases describe the cognitive shortcuts people use when making judgments under uncertainty. Within social psychology and behavioral economics, these shortcuts allow individuals to form rapid evaluations without engaging in computationally demanding analysis, making them central to how human reasoning operates under real-world conditions of limited information, limited time, and finite cognitive capacity. Because people rarely have the resources to calculate every probability, weigh every variable, or reason through every alternative from first principles, the mind relies on approximate strategies that often work efficiently enough to support action. Yet the same mechanisms that make judgment tractable can also generate systematic distortions in perception, probability estimation, attribution, and decision making. For that reason, heuristics and biases are not simply a catalogue of human error. They reveal something deeper about cognition itself: reasoning is adaptive, resource-bounded, and shaped by environments of uncertainty rather than by the abstract standards of perfect rationality.
